Adding the website as an application in IIS

I have a website deeloped in ASP.NET and I want it to be accessed via local URL, for eg: http://localhost/website20

I tried once but the CMS in my website started giving error "It is an error to use a section registered as allowDefinition='MachineToApplication' bey开发者_运维问答ond application level. This error can be caused by a virtual directory not being configured as an application in IIS." Please help about the steps I need to follow.

Create a virtual directory for your site, either in VS project properties or in IIS, depending on type of VS project template you are using.

Steps maybe a bit different depending on which Win ver and IIS ver you have, but you have to go to Control Panel -> Administrative Tools -> IIS -> then on the default website hit right click and do "Create Virtual Directory".
